PAPER BOX. f'

Application filed. August 10, 1925. Serial No. 49,434;

My 'invention relatesV to the ymanufacture of boxes and particularly tothe manufacture of heart-shaped cardboard boxes such.

as are used more particularly for candy.

cost of such boxes by eliminating the hitherto costly hand-manufacturenecessitated by forming the sides of the boxv in a curve which made itimpossible, from a practical standpoint, to form the bottom and sides ofthe box in one piece or to make the box by automatic machinery. Iaccomplish this ob- `ject by making the sides of the .box in straightsections approximately following a heart shape contour, and applying abase or cover sheet to thebox which is heart shape in contour, and sonearly coincides with the side wall of the box that there is nounsightly diiference between the wall of the box and the base or cover.

In the accompanying drawings which illustrate a selected embodiment ofmy in-\ Figure lis an outline of the blank from which the box is made,the scoring and bending lines being indicated by dot-and-dash lines.

VrFigure 2 is a top view ofthe box with the side wall forming portionsbent into their proper position. Figure 3 is a top view of the completedbox.

Figure 4 is a perspective view of the box vwith a similarly made lidassembled therewith. Y Y

The blank illustrated in Figure 1 consists in a body portion 1 roughlyheart-shaped in outline and more specifically comprising a rear portion2 in the shape of a rearwardly tapering trapezoid, the length of whichsubstantially exceedsV the width, a contiguous middle portion 3 in theshape of a forwardly tapering trapezoid of the same base length asportion 2 but substantially wider than portion 2, and a contiguousJforward portion 4 in the shape of a triangle with an angle directedforwardly. Each of the exposed edges of the body portion l is providedwith a rectangular tab 5, the length of which corresponds to the lengthof the respective straight portion and the width of which corresponds tothe desired depth of the box and of course is uniform for all the tabs.

side wall for the box as indicated in Figure- 2. A strip of paper 6 isthen pasted around vthesides of ther box to, hold the tabs 5 in theirwall forming positions. The top edge The object of my invention is tolessen the of said strip may. be turned over -the top edges of the tabsand pasted to the inside wall surface in the rusual manner.

A truly Vheart-shaped base 7 is then appliedto the outside surface ofthe box bottom '1 and it will be noted that the outline of base 7substantially circumscribes the polygonal box body, the slight marginsbetween the intermediate portions of the straight side wall sections ofthe box and the edge of the curved base forming a continuous .projectinglip, such as is ordinarily provided on heart-shaped boxes having curvedwalls, but varying in extent throughout its length.

In the box described, the rear portion consists of a straightr wall 8extending in a straight line from a point on the upper outer edge of onelobe of the curved base 7 past the rear intersection 9 of the baselobes, past the upper intersection of the lobes at the oentervof thebase to a point on the upper outer edge of the other lobe. Relativelyshort side wall sect-ions l0 extend from the` ends of portion 8outwardly and forwardly and longer side wall sections 11 extendforwardly and inwardly from the ends of sections 10 and join at 12 in aforwardly directed point adjacent to the lower intersection of thelobes.

While I have described the bottom and ture may be duplicated toA formthe box ylid having portions 7, 10, 11a, and 12a corresponding to thesimilar port-ions of the box proper. Y

The construction of a heart-shaped box with kstraight wall sectionswithout departing from the general appearance of the box and theretaining of a heart-shaped bottom and lid with curved edges makes itpossible to supply the trade with heart-shaped boxes ata fraction of thecost of such boxes heretofore. Obviously the exact number of straightsections may be varied and I contemplate such and similar modificationsin the commercial development of my invention as are included in thescope of my claims.

I claim:
